I had a Sony CDP555ES. It wasn't something i think would compete with the Pi+Allo combination i have now. What i heard from it was pretty typical of every CD player i have heard. I imagine the BBOA made the tone better but can the opamp help with Jitter?
One you get away from all of those moving mechanical parts in CD players, everything gets significantly better IMO.
Macca made a point that digital is far better when you have sufficient quality amplification. I would totally agree with that. Analogue has sounded great on every amp i have had but digital has struggled to lay a scratch on the vinyl in comparison. Now I am running the Krell and removed as much of the mechanical aspect of digital replay, the sound easily compares with the vinyl and considering the vinyl front end is worth around £4K and the Raspberry Pi, Allo Dac and LPSU cost me under £200, its absolute sickening. I am seriously considering chucking my analogue set up on ebay while it still has value, but i'd never sell my vinyl so i may as well keep it. That's probably the only reason it's still here.
I have never been concerned previously, that Vinyl would be killed off. CD has still got it's finger nails on the edge of the cliff in terms of sales but i will say this with utter confidence, As soon as someone makes the Pi + DAC a plug and play device with this level of quality, it WILL take over. The only thing holding it back is the lack of support when setting one up. Acronyms like NAS, J25 blah blah blah are not user friendly. How DO you set up a NAS? Do you pay? where do you get the files from? How do i connect a pi to Volumio? How do i create an image file? What is mounting a file? Do i plug the pi into the Router? What CAT cable should i use? Is wifi ok? .........AND MORE. That is the barrier to the Pi being in every living room in the country. Thats also why CD players and Vinyl still get played. They do all the work for you. Connect it up, switch it on drop the needle or put a disc in and you are good to go.
This, in my opinion, is the only barrier to world domination for the new generation of streamers.
